first and second shoulder straps that overlap and cross at a dorsal crossing point with the first and second shoulder straps passing through slots in a dorsal plate located at the dorsal crossing point;
a waist strap; and
a rigid dorsal force-transfer member with an upper end that is removably connected to the first and second shoulder straps at the dorsal crossing point of the first and second shoulder straps and with a lower end that is removably connected to a dorsal portion of the waist strap,
